PHP implements Magic methods and about standalone instances and connected instances

This article mainly introduces the implementation of the Magic method of PHP and about the independent instance and connected instances, interested in the friend's reference, I hope to help you.

Specific as follows:

<?php//Magic Method//When containing multiple classes//1. Magic method for automatic loading of classes __autoload () function __autoload ($classname) {if (Isset ($classname)) {require_ Once $classname. " Class.php ';}} /* $computer 1=new computer (), $computer 1->addlist (' Dalisng ', 234); Echo $computer 1; *///__call () mask the error generated when invoking the method, and when we call a nonexistent method, the __call () method is called automatically. Independent instances, each of the two instances were established, each non-interference $computer2=new computer (); Echo $computer 2->name;echo "<br/>"; $computer 3=new Computer ( echo $computer 3->name;echo "<br/>", $computer 3->name= "big bright"; Echo ' $computer 3->name: '. $computer 3- >name;echo "<br/>", Echo ' $computer 2->name: '. $computer 2->name;echo "<br/>"; echo "
Computer.class.php

<?phpclass computer{public $name = "1234"; function __construct () {echo "You is right!";} function __call ($methodName, $argsList) {//This method is called automatically when the method does not exist, $argsList is the corresponding parameter echo $methodName. " () method does not exist! "; echo "<pre>";p Rint_r ($argsList); echo "</pre>";} Private Function __tostring () {///when the user outputs a string that does not exist, the method automatically calls the Echo object name echo "I am the object's string!" ";}}
Summary: The above is the entire content of this article, I hope to be able to help you learn.
